The SEMIKRON SKM300GA128D is a high-current, high-voltage IGBT module rated for 300A collector current and 1200V blocking voltage. Built on SEMIKRON's proven trench-gate IGBT technology, this module incorporates an antiparallel freewheeling diode optimized for low recovery losses, making it well suited for demanding switching applications where efficiency and thermal management are critical. The SKM300GA128D is housed in a robust, industry-standard package designed for reliable pressure-contact or screw-terminal mounting and simplified heatsink integration in high-power power electronics systems.

The SKM300GA128D is widely deployed in industrial AC drives, servo amplifiers, regenerative converters, UPS systems, and medium-frequency induction heating equipment. Its 1200V voltage class and 300A current rating address the performance requirements of three-phase inverter legs in multi-kilowatt motor drives and traction converters. Rail propulsion auxiliaries, wind turbine converters, and large industrial power supplies also commonly specify this device class. Wherever high switching frequency must be balanced against conduction loss and junction temperature limits, this SEMIKRON module delivers a well-validated solution used by major OEMs worldwide.

Key Features of the SKM300GA128D:

• 1200V VCES blocking voltage with 300A rated continuous collector current for high-power converter stages
• Integrated antiparallel soft-recovery freewheeling diode minimizes reverse recovery losses and reduces switching transients
• Trench-gate IGBT cell structure provides low VCEsat for reduced conduction losses across the operating current range
• Optimized for switching frequencies up to 20kHz, balancing dynamic losses with thermal dissipation requirements
• Industry-standard SKiM / 62mm package footprint enables direct replacement and simplified PCB or busbar interfacing
• Internal NTC thermistor available for real-time junction temperature monitoring and over-temperature protection integration

The SKM300GA128D carries a factory lead time of approximately 29 weeks for new production, a reality common across the SEMIKRON high-power IGBT portfolio given global semiconductor supply constraints. For maintenance operations and production lines that cannot absorb that delay, sourcing through a specialized distributor is essential. ATI Accurate Technology focuses specifically on IGBTs, thyristors, and power modules — including long-lead-time and hard-to-find SEMIKRON parts — giving procurement teams a faster path to critical inventory without waiting on factory queue positions.

ATI Accurate Technology is located in Palmetto, Florida, and ships same-day on orders placed before 5PM EST.
